We rented a car at an online rate that was agreeable for a Hertz #1 Club Gold Member. Due to unforeseen circumstances we needed to extend the rental for another week. Not only did thy not honor the online agreement, but DOUBLED it to the holiday rate! We were billed $1400 for 2 weeks when the original quote for one week plus 3 days was for $460. We will not do Hertz again! This is not our first negative encounter. 3 hours at the airport in San Francisco did not lend itself to the start of a great vacation in wine country. Figure it out Hertz!
